by Martin Green "Water resistance and reliability are what it is all about with a diving watch. Anything that doesn’t contribute to this does not belong on such a watch. This is why the history of diving watches features mainly robust time-only watches. However, advances in technology make it now possible to achieve a water resistance that was unimaginable half a century ago. Also, the reliability of complications has been increased making it now possible to create diving watches the world has never seen before."
